This article will contain spoilers both on how I solved 2022 Day 7's challenge "No Space Left On Device" using SQL, as well as general ideas on how to approach the problem. I recommend trying to solve it yourself first, using your favorite language. This article is delayed from the actual puzzle's release. Also note that my solutions are seldom going to be the "best" solutions - they were solved as quickly as possible, and these articles will show my first solutions, with some minor reformatti...

Many applications running on Kubernetes will send their output to standard error ( ) and standard out ( ). This is a convenient location for log aggregators to collect and consolidate logs. However, some applications like Postgres write their logs to disk so getting the Postgres logs to the log aggregator requires a few special tricks. Crunchy Postgres for Kubernetes recently introduced support for sidecar containers for both Postgres and PgBouncer pods. A sidecar is a container that runs alo...

If you are like us, Tailscale was an obvious tool to add to our network — as soon as we saw it, we knew we needed it. For those who haven’t tried Tailscale yet, it’s best described as a programmable, re-sizeable, distributed private network mesh. Yes, it’s that great. The better part is that Tailscale is fairly simple, and because it’s simple, it is easy to get correct. When we set out to build Crunchy Bridge we wanted to ensure you could build safely from day one. This included features suc...

Time for the annual Advent of Code challenge for 2022! If you are not familiar with AOC, every December a new puzzle is added each day, getting harder as it goes along, and the challenge is to solve it any way you can by transforming an input file into an answer. I'm going to use PostgreSQL and solve things solely with the use of SQL. This article will contain spoilers both on how I solved Day 1's challenge "Calorie Counting" , as well as general ideas on how to approach the problem. I recomm...

JSON is everywhere, even in your SQL database. Since Postgres added JSON support 10 years ago, we've seen widespread adoption. When JSON support was first released in 2012 the implementation was a fairly flat representation of the JSON data type. It had limited querying and indexing capabilities. Craig , who was active in early JSON discussions with Postgres contributors, admits "Postgres cheated" with these early implementations. As JSONB has been introduced and adopted, I think you can see...
